STANDARDS

The atoi() function conforms to ANSI X3.159-1989 ("ANSI C").

CAVEATS

atoi does no overflow checking, handles unsigned numbers poorly, and han-
dles strings containing trailing extra characters (like "123abc") poorly.
Careful use of strtol(3) and strtoul(3) can alleviate these problems, but
strtonum(3) can be used to convert numbers from strings much more safely
and easily.
